No. 3693:

And that is why the Habsburgs not having any blood ties with the Brasebys is not a bluff*, and that any notion that the two families share any blood is completely and utterly erroneous, the big hint being obvious should one merely glance at the tail end of the former dynasty's Spanish line (assuming one can untangle that tumbleweed).

* But it is a forgivable mistake, the Braseby familiy genealogies are so labyrinthine and tangled here, there everywhere, it's spectacularly easy to misread them, even with training. After all, it took me about 14 months just to confirm that Donna Braseby was not the long-lost daughter** of Frédéric Chopin, and I say that as the only member of the Postcard writing team who is able to decipher that jumble without the assistance of five or more interns.

** She was actually the estranged sister of Queen (King***) Jadwiga of Poland. Don't ask.

*** Yes, a female king. Seriously****. It was because at that time a queen was considered to be merely a consort and thus couldn't actually rule, but they wanted her in charge and it turned out there weren't any laws against making a woman a king.
